Can I suspend / hang speakers?


All right, I'm setting up a home theatre for dad (father's day and all), and he'd prefer to suspend the rears from the rafters rather than have stands. It seems...well...you know. Can someone give me a sound technical reason this is a bad idea? Thanks. -Dave

Thank you Wade- Its been over 30 years since I studied any physics. I was just guessing on which law. I'll gladly take you word for it.
Here is required reading for rigging flyable speakers from ATM-Flyware:

If you don't do it correctly, DON'T do it at all.
Poor Issac must be spinning in his grave! Yes, the voice coil will push with equal force on the driver cone and on the speaker enclosure, but Newton also came up with F = M*A, which tells us that movement of the massive enclosure will be tiny.

The only drawback to hanging speakers by chains is cosmetic. If the wife agrees, go for it.
The movement of the enclosure will indeed be small, but given the generally universally accepted goal of rigidly mounting speakers, why in the world would you hang them in space, to let them move (swing) on their own? Imagine a recording with bass almost entirely in one channel, with large excursions of the woofer and small excursions on the other side, sending the imaging info all to !@#$. Remember that our ears/brains use millisecond delays to localize sound. YOu would't consider mounting speakers on a columnar spring which could move around in response to the driver motions; isn't this similar to what you are considering by hanging them? Maybe one of our speaker designer/builders could chime in. Maybe my intuition is completely wrong here.
Swampwalker, be carefull of intuition and "common sense", they are what people use to explain that heavier objects fall faster than light ones.
The movement caused by the counter movement of the speakers can be calculated to be virtually, if not literally, nil.
